LGD046E 75hz->105hz

Post by Vechs » 08 Jul 2019, 08:23

Hello, another laptop, another OC, but it seems that the color accuracy is far worse when oc'd, it shows up as 6bit color depth, not 8 bit color depth, no frameskipping or whatsoever. Gotta ask, is there an fix for that color depth issue or that is not fixable?

Thanks for this overclock report!

One workaround for the color depth is GPU-based temporal dithering, but that is a feature that may not be enabled on a laptop GPU. Basically GPU FRC replacing monitor FRC.

You may be SOL with 6bit though, so it will be your judgement call whether your nearly-50% overclock benefit outweighs the color loss. Probably not for static content, but possibly for fast-action content if your laptop GPU is powerful enough for high framerates in some games such as CS:GO.
